Light for Them that Sit in Darkness is a â€śDiscourse of Jesus Christâ€ť by John Bunyan. This treatise was originally published in 1674 with the purpose of correcting some doctrinal issues concerning the gospel which were running rampant at the time.

Free from his incarceration at the Bedford Jail for two years (after 12 years in prison), Mr. Bunyan exhorted his readers to embrace a pure gospel, a Biblical gospel. Bunyan viewed the Person and work of Jesus Christ the mainspring from which every aspect of acceptable Christianity was produced, be it doctrinal, dutiful or devotional. â€śGood works must flow from faith, or not at all,â€ť wrote John Bunyan in his 1663 treatise, Christian Behaviour (first published in 1674).
